Ok, I admit, I have sailed uni rigs for so long, that I forgot about the sagging jib. Well, take higher gauge bridle wires and stiffen the hulls in front of the front beam, and your job is done... or sail uni.

And by the way I touched a X40 boom as much as you sailed on Slingshot .
I would never propose to replace a CFRP boom or mast by wood. But a wooden hull of a small beach cat... as long as you or your builder knows how to build it. Today it is hard to find someone who can.

Oh wow, a boat is a black whole which absorbs energy. Did you ever thought what happens, when structures reflect after removing a load?
